โฆ Synopsis
Previous articles compared and analyzed the pseudorandom number generators that are delivered with offthe-shelf Fortran compilers for personal computers, and updated two CPC library elements to support multiple Fortran compilers. In the current work, the standard generator that is provided with Salford Software's FTN77 compiler is examined, and the two existing CPC generators are migrated to use that compiler's in-line assembler feature. Statistical analyses are presented that pertain to both the current software, and to that of the previous articles.

We carry out an in-depth analysis of the multiple-recursive matrix method for uniform pseudorandom number generation which was introduced in an earlier paper of the author. This method yields much larger period lengths than the GFSR method with the same order of the recursion and the same precision.
The feasibility of random number generation using microcomputers is discussed and the appropriateness of alternative algorithms is evaluated on the basis of several criteria of statistical randomness. The relative deficiencies of each algorithm are cited and a modified Fibonacci generator is recomme
The multiple-recursive matrix method is a general linear method for the generation of uniform pseudorandom numbers and vectors which was introduced and studied in earlier papers of the author. In this paper we improve on various bounds in this method by using information on -splitting subspaces of f
